rlhis invention relates to hydrocarbon motors, and particularly* to mixture heating means therefor. y t

One of the objects of the invention is to 5 provide a hydrocarbon motorwith carbureting and mixture heating means of extremely simple and eificiert form.

Another object of the invention is to provide agcombustionheater as an integral part l0 of the motor intake elbow.

Another object of the invention is to provide a combustion heater with a combination inlet andl observation window.

Another object of the invention is to provide a combustion heater with mixture feeding means having an adjustable air inlet to insure a more nearly correct mixture for 'the Other objects and advantagesof the invention will appear from the following description taken in connection with the drawf ings which form a and in which- Figure lis a part of this specification,

ing this invention;

Figure 2j is a section on the line 2-2 of` Referring to thev drawings,10 indicates a portion of amotor cylinder block which may comprise one or more cylinders, and 11 is the intake passage in said block leading tothe motor Aintake valves.

12 represents the upper portion of a car 7 buretor Whichmay be of any suitable form, the form shown, however, beingof the well known Packard type in which a Venturi mixing tube 13 surrounds the Gasoline noz- Jzle 14, which nozzle is vconnected to the usual floatv chamber, not shown in the drawings. By the suction of the motor the air and gasoline `supplied by the tube 13 and nozzle 14 respectively are mixedin the upper part ot' rthetube 18 andpass upwardly therefrom in the form of a combustible mixture. j

Between the carburetor and the motor an intake elbow 15 whichis usuvallyfa castingr having a flange 16 secured Vto the upper -endof the carburetor 12 and having a bent intake passage or conduit 17 for carrying the mixture from the carburetor' 12 to the invvertical section through` aI 25 motor intake elbow and carburetor, embody take passage lllof theinotor. .A throttle valve 18 is shown as arranged in the horizontal part of the passage 17 near its ontlet end. The throttle valve is voperated by suitable connectionsa-nd arms 19 and 2O are adapted' to abut against a stop 21 `which .de-

termines its extreme positions. The throttle valve is shown in closedposition for idlingA the motor,` only a small amount of mixture being allowed to pass it.

The upper par't of ,the casting or elbow `15 i 'is formed with a jacket 22, thespace inside i of this jacket forming a combustion chamji ber23 of a combustion4 heater. The cornbustion chamber .has an outlet 241C'` into vthe inl take conduit 17 .beyondthe throttle valve 18 j so that the'cornbustion chamber`23 is always course this suction is unusually: highl when the throttle valve is closed,L aSfshown in the drawing, becauseat that ltime the motorist` idling and the .carburetor is substantially' shut oit from the motor texceptthrough the combustion chamber 23, as will' hereinafter appear.` Y f j The mixture 4withdrawing means'for ther combustion chamber 23 comprises an opening or port 25 which is arranged in the bend of the elbow immediately above theV carburetor 12, and a passage'26which leads.

V.subject to' the suction'` of the motor. 'OL v upwardly through a'portion of the casting I 15 to the upper part of an enlargement or boss 27 shown as formed as an integralu part of said casting. "The opening'25` is so ar ranged in the bend -of the passage 17 that it is adapted 4to receive a portion of the mire, ture on its way from the carburetor -12to the motor cylinders, and in some casos it is'` found that whilethisl mixture as ay whole is just suitable for the motor, that part of it which is withdrawn for the combustion chamber is a little richerfthan is 'required for the best operation ofthe heatenv In such n particularly in Figure 4, and., a manually cases an air` inletport`28 is providedvnear 'i `the`upper end of the passage 26, as shownv adjustable'needle valve 29 is proyide'd forel regulatmg 1111 Size of or cutting oit entirely j this air inlet port2i% e Y j t Thecombustioncharnber 2`3fmay be of any suitable size .or shape', but it is shown as jacketing the. upper wall lofthe horizontal@ part ofthe elbow ,15"andthe chamber is slightlyv enlarged at one end as shown at 30 and a spark plugl is threaded into one side or burnt gases from the combustion chamber 23 -will be expelled through the outlet 24 where they will meet the mixture passing to the motor and heat it to a suitable temper# ature for iii-ing in the motor cylinders. Also, some of the heat from theburning of the mixture will pass through the wall of the intake elbow and keep the elbow hot to thereby assist in vaporization. Likewise the passage 26 is kept hot so that, the tempera' ture of the mixture passing therethrough will be raised and thereby make it more readily ignited when it reaches the combus-.

tion chamber.

The boss or enlargement 27 above referred to is arranged directly above the spark plug 3l and is drilled out as shown at 32, the drilled out part being open at the upper end of the boss. A screen 33 is set into the boss immediately over the spark plug and an inlet plug 34 is set in on top of the screen so that it retains the latter in place. This in let plug is hollow and it is formed with an exterior annular passage 35 which is in communication with a branch 36 of the passage 26,. and the plug 34 is also formed `with'a somewhat oft'set inlet port or passage 37 leading from the passage 35 to its interior. This offset arrangement of the port 37 causes the gas to descend spirally through the plug 34 and to pass through the screen 33 in a' well mixed form so that it is readily 'ignited by the spark plug.' 31 immediatelybelow the screen.

A glass or other transparent window 38. is arranged directly above the plug 34 be'- tween suitable washers 39 and a hollow-nut 40 is threaded into the upper end of the boss 27 andl`retains the screen, the plug 34, and the glass 38 in place.

This arrangement of the inlet plug 34 and glass window notonly makes a cheaper and more readily assembled construction than heretofore, but it also places the glass in the coolest part of the combustion chamber without in any way interfering with the function of the window. Because of the 'entrance of therelatively cool gas just bespecifically claimed, but it will be understood that the invention is not limited to the exact details of construction shown, as it l. A combustion heater comprising a com bustion chamber, a spark plug, a window -for said chamber, and mix-turc inlet means for said chamber between the spark plug and the window.

2. A combustion heater comprising a combustion chamber, a window in the upper part thereof, a spark plug having its sparking point below the window, and `mixture inlet means for said chamber between the window and the spark plug.

3. A combustion heater comprising a come bustion chamber, a mixture inlet/plug for.

said chamber, a glass window outside of said plug, and a hollow nut for retaining said window and plug in place.

4. A combustion heater comprising a conibustion chamber, a mixture screen, a mixture inlet plug outside of said screen, a glass window outside of said plug, and common means for retaining said screen,'plug and window 1n place.

5. A combustion heater comprising a com.

8. In a hydrocarbon motor, the combinar tion with a motor cylinder, ofa carburetor. and an elbow intake conduit between'sai carburetorand said cylinder, a combustion chamberhaving an outlet connection to said elbow. beyond. the throttle valve, mixture withdrawing means at the bend in said elbowiand connected to supply mixture to said .combustion chamber, and air inlet means for thinning the mixture withdrawn for said combustion. chamber.
